Description

This PR fixes a security issue where the module manifest path was being leaked in SystemExit error messages in src/spark_cli/cli.py.

actual_behavior

SystemExit error messages at cli.py lines 1973, 1975, and 1977 interpolate the full {manifest_path} variable, leaking internal filesystem paths to the end user.

expected_behavior

Error messages should describe the problem generically without revealing filesystem paths to users.

repro_steps

1. Trigger a FileNotFoundError, PermissionError, or TOMLDecodeError in load_module() in src/spark_cli/cli.py.
2. Observe the SystemExit message contains the full filesystem path.

Changes

• Line 1973: Module manifest not found: {manifest_path} → Module manifest not found: module manifest
• Line 1975: Permission denied reading module manifest: {manifest_path} → Permission denied reading module manifest: module manifest
• Line 1977: Invalid TOML in module manifest {manifest_path}: {exc} → Invalid TOML in module manifest: {exc}

before_after_proof

Before: raise SystemExit(f"Module manifest not found: {manifest_path}") at line 1973, raise SystemExit(f"Permission denied reading module manifest: {manifest_path}") at line 1975, raise SystemExit(f"Invalid TOML in module manifest {manifest_path}: {exc}") at line 1977.

After: raise SystemExit("Module manifest not found: module manifest"), raise SystemExit("Permission denied reading module manifest: module manifest"), raise SystemExit(f"Invalid TOML in module manifest: {exc}"). The manifest_path variable is no longer interpolated into any message.

tests_or_smoke

Verified via grep that {manifest_path} no longer appears in any SystemExit message in the affected file. Change is purely string substitution with no behavioral side effects.

duplicate_notes

Searched open PRs and issues for the same manifest path leak in SystemExit messages; this packet covers the spark-cli load_module error handling path. No existing PR addresses this issue.

risk_notes

No secrets, CI workflows, dependency files, private owner routing, or prompt surfaces changed. Change only affects error message strings. Low risk: no logic or control flow altered.

review_claim

• Impact claim: medium
• Evidence types: before_screenshot, after_screenshot, smoke_test
• Review state requested: pr_review

Impact

This prevents sensitive filesystem path information from being exposed in error messages, improving security.
